[RESEND PATCH v5 0/3] Support for USB DRD Phy driver for NS2

From: Raviteja Garimella

Resending the patchset v5.
Commit message for dts patch is edited as suggested by Florian.

Changes in v5:
=============
Removed references to phy_ops in the same driver by connect_work
event handler to change the phy modes.

To support dynamically changing the mode of the phy, it does
not require doing a phy reset/programming of PHY PLL. Changes
are made to the connect_work routine to just program the required
register bits to achieve this purpose.

Changes in v4:
=============
Remove references to edev->name in debug prints.

Changes in v3:
=============
Remove unnecessary checks for poweron as suggested in review.

Changes in v2:
=============
1. Initialize file operations .owner field with THIS_MODULE.
2. Remove unnecessary gpio example in DT bindings documentation.
This is previously acked by Rob Herring <robh@xxxxxxxxxx>

Introduction for PATCH v1:
